Winner of Valve's Summer Mapping Initiative! A 30-minute level of intermediate difficulty with four chambers set in the destroyed Aperture Science facilities. Some puzzle elements include hard light surfaces, discouragement beams, aerial faith plates, and excursion funnels. Suggestions, reviews, praises, criticisms, and all other feedback welcome. Enjoy.
I can see why this won. It's great to look at, and every time you get stuck it's purely because you weren't thinking with portals! :)
